Mar 31: Deutschland

This track is by the German rock band Rammstein, known for their massively over the top stage shows.

Their 2019 track, which marked their comeback after ten years of no new music, was accompanied by a nine minute video which takes a bit of explaining. There were also some band controversies. 

Warning: the video contains some violent imagery and the links contain a few rude words

It is a history of Germany, starting in Germania Magna in 16 AD according to the caption.

More details on the imagery in the video in the Wikipedia article above.

The lengthy music video sparked controversy; its dark, violent, and macabre style—typical of the band's aesthetic—features various events from German history, including Roman times, the Battle of the Teutoburg Forest, the Middle Ages, witch hunting, the November Revolution, the Golden Twenties, Nazi book burnings, the Hindenburg disaster, the First and Second World Wars, the Holocaust, the Weimar Republic, the Red Army Faction, and the division of the country into West and East Germany; it also features science fiction scenes set in outer space, cannibalism in which people eat Germania, the personification of Germany, and a bank robbery featuring lead singer Till Lindemann crossdressing as Ulrike Meinhof. The Afro-German actress Ruby Commey appears as Germania throughout the video.
